[Tex/LaTex] Labeling in Mathematica to match the font size same as in LaTeX

Question

I have some plot

Plot[a, {a, -6, 6}]

I need to use it in Latex. However the problem is that labeling text style in Mathematica does not match with LaTeX text. So what I do, I copy the figure without labels from Mathematica as

\documentclass[a4paper,pra,preprint]{revtex4}
\usepackage{graphicx}

     \begin{document}
\setlength{\unitlength}{2cm}
 \begin{picture} (6,5)


\put(5.12,1.15){$0$}

\put(3.0,2.6){$0.3$}
\put(3.0,3.85){$0.6$}


\put(3,1){\includegraphics[width=8cm,height=6cm]{a2.png} }
 \put(2.9,2.15){$-6$} 
 \put(6.9,2.15){$6$} 
 \put(4.8,3.9){$6$}
  \put(4.8,1.0){$6$}
\end{picture}
\end{document}

and place labels manually in LaTeX as

As there is a clear difference in label style fonts.
This technique is not only tiring but it will not support me to save the labeled figure in .png or .eps format. Rather it will be a .pdf generated.
Is there a way to match the label font style and size of labeling text in Mathematica?

Answer 1

I found the solution actually. By selecting the Font Style of Times Roman in MikteX by using package

mathptmx

And by selecting Label style in Mathematica as

LabelStyle -> Directive[ FontFamily -> "Times"]

worked for me.
